THOMAS FEARON, OF YONKERS, NEW YORK.

STEAM-GENERATOR.

SPECIFICATION forming part of Letters Patent No. 486,098, dated November 15, 1892.

Application filed December 14,1891- Serial No. 414,943. (No model.)

which the following, taken in connection with; the accompanylng drawings, is a full, clear,-

and exact description.

My invention relates to an improved steamgenerator of somewhat similar construction to that shown in my pending application, Serial No. 391,215, filed May 1, 1891, capable of pro-' ducing a maximum degree of steam with a minimum amount of fuel and requiring for repair the exercise of a minimum degree of skill or ingenuity; and to this end it consists, essentially, in a head extending laterally from one side of the generator, a series of heatingtubes projecting from said head and arranged in planes one within the other, whereby the tubes may be successively screwed or otherwise secured in the desired position, an upright head connected to the opposite extremities of the tubes, and a steam-drum arranged above the tubes and connected to said head.

The invention furthermore consists in a seriesof these independent heads arranged at opposite sides of the fire, heating-tubes lapping one with the other and inclining upwardly at their free extremities, upwardlyextending heads, separation-dru ms between the steamdrum and the upwardly-extending heads, and connections between the watercontaining base and the separation-drums, and in the detail construction and arrange ment of the parts, all as hereinafter more particularly described, and pointed out in the claims.

In describing this invention reference is had to the accompanying drawings, forminga part of this specification, in which like letters indicate corresponding parts in all the views.

Figure 1 is aside elevation of my improved invention,a portion of the outer casing'being shown in section. Fig; 2 is a longitudinal sectional view taken on line 2 2, Fig. 1, for further illustrating the construction of the parts of my invention. Fig. 3 is a transverse sectional view taken on line 3 3, Fig. 2. Fig. 4 is a horizontal sectional view taken on line 4' 4, Fig. 1. Fig. 5 is a sectional detail View for representing one of the plugs in the upright heads of my generator, and Fig. 6 is an elevation of a modified form of my invention.

The water-containing base A of my generator is preferably rectangular in form and is composed of the side pipes or heads a a and the front and back pipes a a which may be of smaller diameter than the pipes or heads a a.

B represents heads extending laterally from the opposite sides of the generator and preferably disposed in a slightly-inclined plane above the combustion chamber 0. These heads B are preferably independent of each other and are connected to the pipes or drums a a by tubes b of less cross-sectional area than the heads B.

Opening from the laterally extending drums are the heatingtubes D, which are usually arranged in planes one within the other and withtheir extremities inclining upwardly to facilitate the circulation and augment the efficiency. It will thus be noted, as best seen at Figs. 1 and 3 of the drawings, that one extremity d of the tubes is turned downwardly and the other d disposed in an inclined plane. By arranging the heatingtubes as aforesaid their lower downturned extremity may be suitably secured to the laterallyextending head B, as by screwing the same into said head,and then one by one the heating-tubes adapted to be disposed in the next adjacent planes may be likewise successively secured in position, thereby greatly facilitating the construction of the generator. The upper extremity of the heating-tubes D discharge into an upright head E, disposed, preferably, in a plane at right angles to the plane of said upper extremities d of the tubes D, and, as best seen at Figs. 1, 2, and 3, the head E is connected to the adjacent pipe or drum by a short nipple e of less diameter or cross-sectional area than the head E. The upper ends d of the tubes D are expanded into the head E, and to facilitate thisconstruction I'form said head with a series of, apertures 6', arranged opposite to the tube extremities for permitting the entrance of an expanding-tool and adapted to receive removable plugs E, Fig. 5.

, From the foregoing it is apparent that the head B, its connecting-pipes b, the heatingtubes D, and the headE and its connecting- IOO nipple e form one of the generator-sections A',and upon reference to the drawings it will be noted that the generator is composed of a number of these sections, alternating with each other and so arranged that the heatingtubes of one section incline in a reverse direction to the corresponding tubes of the other section, thereby producing a series of oppositely-flowing, quick, and positive circulations from side to side of the generator, which, I have observed, is a particularly effective method of generating steam. Moreover, in the aforesaid construction the water-containing heads B are directly above the combustion-chamber, and it is evident that the water is subjected to a very great degree of heat at the commencement of its circulation, which is augmented as the water-reaches the center of the heating-tubes.

F represents a steam-drum mounted above the tubes D and extending from frontto back within the generator above its central portion. This drum is connected to the separate beads by pipes g and g',between the ends of which is interposed a separation-drum G for permitting the separation from the steam of any water carried by the same into the pipe g. The separate heads E are each provided with a separate steam-discharge pipe g, although but two pipes g at the opposite extremities of the separation-drums G are discharged into hubsf, formed at the ends of the steam-drum; but it is evident that more of these pipes g may be used if desired. The water is conducted from the separation-drums by means of pipes G discharging into the water-containing base A, and in order to facilitate the separation of the steam and water these drums G are preferably disposed slightly below the upper extremity of the heads E, and the pipes g,discharging thereinto,inclineslightlydownward.

To further obviate the presence of water within the steam-drum F, I provide a pipe or pipes f, which may extend downwardly from one or both extremities of said drum and discharge into the water-containing base A.

Steam is taken from the upper portion of the drum by means of a pipe I-I, extending downwardly to about the central portion of the heating-tubes, and is there passed through coils 7L in said pipe, which extend from front to back of the generator between the heatingtubes and serve to superheat the steam for increasing its efiiciency, the heatingtubes being formed with deflected portions D for permitting the easy passage of the coils h.

At Fig. 6 I have shown a modified form of my invention, in which the laterally-extending heads B are arranged at one side only of the generator, the upright head E at the other side, a single separation-drum G at one side of the steam-drum F, and the superheatingcoils just above the outer end of the laterallyextending head E; but this is evidently no departure from my invention.

The operation of my generator will be readily perceived from the foregoing description and upon reference to the drawings, and it will be particularly noted that the same is provided with a great amount of heating-surface, the tubes being so arranged that the circulation is rapid and effective; that the parts are compactly assembled and all water separated from the steam discharged from the heating-tubes, so that the presence of water within the steam-drum is entirely obviated; that the steam is superheated by means of coils disposed bet ween the heating-tubes, and that any one s ction of the generator may be quickly and readily removed for any desired purpose and the generator then tired without inconvenience after the openings in the side drums at a and the distributing-drums have been suitably plugged. I have here shown a portion of the outer shell A for indicating the general contour of the same; but this shell forms no part of my present invention, and as my generator is not limited to any construction of grate or supporting-base I have neither shown nor described such parts. It is evident, however, that the construction of my generator may be somewhat varied from that shown and described without departing from the spirit of my invention. Hence I do not limit myself to such precise construction and arrangement.
